First of all, this is off-topic for any FreeBSD list. They're cc'd only to let 
them know someone has told you this. I would suggest trying a PHP list, 
but...

... you can't do this with PHP. You're viewing a (pure HTML) page generated by 
PHP, and for anything to change on it, the page needs to be regenerated, e.g. 
reloaded.
